The human canstatin cDNA was amplified by RT-PCR and then directionally cloned into pU? expression vector. The recombinant pU?-Can vector was connected with the screening marker (bar box), to construct a eukaryotic expression vector called pU?-Can-Bar. This expression vector was introduced into the D.salina by glass beads method. The screening culture of transformants of D.salina was performed in solid media containing 5 ?g/ml PPT, and the analyses of transformants were carried out through PCR and Southern blot. PCR results revealed that specific 700 bp products were detected in the different transformants of D.salina but not in negative control. Southern blot analysis further demonstrated that human canstatin gene was integrated into the D.salina genome. Moreover, the results of genetic stability analyses of transformants demonstrated that canstatin gene was stably inherited in the D.salina transformants. The successful preparation of the D.salina transformants will provide the experimentation evidence for producing canstatin protein cosmically by using the D.salina bioreactor and give a better prophase work basis for clinic application of canstatin protein early.

Objective To investigate the mRNA and protein expression levels of interferon(IFN)-?in the peripheral blood of patients with systemic lupus erythematosus(SLE),to analyze the relationship between IFN-?and disease activity,and to evaluate the role of IFN-?in the pathogenesis of lupus.Methods SYBR green dyeⅠbased real-time quantatives PCR method was used to compare the mRNA expression levels of IFN-?in the peripheral blood leucocyte of SLE patients and healthy controls.Surum levels of IFN-?were measured with ELISA method.Results IFNA1 mRNA expression level in SLE patients(2.8?3.5)was signifi- cantly lower than that of normal controls(12.7?10.7,P=0.000).There was no significant difference between patients treated with glucocorticoid and those without in the expression level of IFNA1(P=0.549).Serum levels of IFN-?in SLE patients was significantly higher than that of normal controls(P=0.003).The SLEDAI score and anti-dsDNA antibody correlated positively,and complement components C3,C4 and leukocytes correlated negatively with serum concentration of IFN-?.IFN-?level correlated with the presence of fever and rash. Conclusion The close relationship between IFN-?serum level and disease activity in SLE patients suggests that IFN-?might be of importance in the disease process.

Identification accuracy of traditional Chinese medicine is crucial for the traditional Chinese medicine research, production and application. DNA barcoding based on the mitochondrial gene coding for cytochrome c oxidase subunit I (COI), are more and more used for identification of traditional Chinese medicine. Using universal barcoding primers to sequence, we discussed the feasibility of DNA barcoding method for identification commonly-used medicinal snakes (a total of 109 samples belonging to 19 species 15 genera 6 families). The phylogenetic trees using Neighbor-joining were constructed. The results indicated that the mean content of G + C(46.5%) was lower than that of A + T (53.5%). As calculated by Kimera-2-parameter model, the mean intraspecies genetic distance of Trimeresurus albolabris, Ptyas dhumnades and Lycodon rufozonatus was greater than 2%. Further phylogenetic relationship results suggested that identification of one sample of T. albolabris was erroneous. The identification of some samples of P. dhumnades was also not correct, namely originally P. korros was identified as P. dhumnades. Factors influence on intraspecific genetic distance difference of L. rufozonatus need to be studied further. Therefore, DNA barcoding for identification of medicinal snakes is feasible, and greatly complements the morphological classification method. It is necessary to further study in identification of traditional Chinese medicine.

To identify some medicinal animals of Lacertilia, in total 59 individuals belonging to 12 species 7 genera 3 families, we used the universal barcoding primers to sequence these species, compared with other homologous sequences (564 bp) obtaining from the GenBank and finally constructed phylogenetic trees using Neighbor-joining, Maximum parsimony and Bayesian inference, respectively. As a result, the mean content of G + C (46.5%) was lower than that of A + T (53.5%). As calculated by Kimera-2-parameter model, the whole individuals mean distance for interspecies and intraspecies was 35. 5% and 1.7%, respectively. The mean distance for interspecies was 21 times as much as that for intraspecies. The mean distance for intraspecies of Gekko swinhonis, Hemidactylus frenatus and G. gecko was greater than 2%, respectively. Further analyses suggested that geographical groups of the three species might be of different subSpecies, even species. Of course, incorporating morphological characters and other unlinked genetic markers in future studies will offer further insights into the divergence. On the basis of phylogenetic trees constructed by COI, our results indicated that the taxonomy of the category (family, genus, and species) by DNA barcoding is consistent with morphological characters. Therefore, DNA barcoding is a useful tool for both identification and phylogeny of medicinal animals of Lacertilia, particularly for nonprofessor identifying authentication of Chinese crude drugs of these species.

OBJECTIVETo explore the clinical characteristics of Wolman disease and diagnostic methods using enzymatic and molecular analysis.

METHODLysosomal acid lipase activity was measured using 4-methylumbelliferyl oleate in the leukocytes of an infant suspected of Wolman disease and LIPA gene mutational analysis was performed by PCR and direct sequencing in the proband and his parents. After the diagnosis was confirmed, the clinical, biochemical, radiological and histopathological findings in this case of Wolman disease were retrospectively reviewed.

RESULTThe sixteen-day-old boy was failing to thrive with progressive vomiting, abdominal distention and hepatosplenomegaly. Abdominal X-ray revealed adrenal calcifications which were confirmed on abdominal CT scan. Xanthomatosis were observed on enlarged liver, spleen and lymph nodes during abdominal surgery. Liver and lymph node biopsy showed foamy histiocytes. The lysosomal acid lipase activity in leukocytes was 3.5 nmol/(mg·h) [control 35.5 - 105.8 nmol/(mg·h)]. Serum chitotriosidase activity was 315.8 nmol/(ml·h) [control 0 - 53 nmol/(ml·h)]. The patient was homozygote for a novel insert mutation allele c.318 ins T, p. Phe106fsX4 in exon 4 on LIPA gene. His both parents were carriers of the mutation.

CONCLUSIONThe clinical features of Wolman disease include early onset of vomiting, abdominal distention, growth failure, hepatosplenomegaly and bilateral adrenal calcification after birth. A plain abdominal X-ray film should be taken to check for the typical pattern of adrenal calcification in suspected cases of Wolman disease. The enzymatic and molecular analyses of lysosomal acid lipase can confirm the diagnosis of Wolman disease.

OBJECTIVETo develop a standard Neglect Evaluation Scale which is suitable for rural primary school students in China.

METHODSAccording to the principle of multi-stage stratified cluster sampling, a field investigation was conducted among primary school students in 28 counties from 7 provinces and 2 municipalities. The questionnaires were self-designed, and determined by multiple rounds of pilots and revisions. Among 5 862 students, 2 792 (6-8 years' old) and 3 070 (9-11 years' old) were investigated by using two kinds of Neglect Evaluation questionnaires, respectively. After project analysis, factor analysis, reliability and validity analysis, the reliability and stability of the scale were tested. Then percentile method was used to determine the evaluation standard to develop and finalize the formal scale.

RESULTSThe numbers of the remaining items for 6-8 year-old group and 9-11 year-old group is 69 and 58, respectively, both of which contain six levels of neglect, including body, emotion, health care, education, security, and society. 4 times of factor analysis were conducted in both of the two groups. The factor loadings in these two groups were 0.290-0.700 and 0.276-0.729 respectively. Reliability test results showed that the two kinds of scales' Cronbach alpha coefficient were 0.924 and 0.929 respectively, split-half reliability were 0.891 and 0.904 respectively, the retest reliability were 0.559 and 0.892 respectively, the differences were statistically significant (P < 0.05). The retest reliability among 6-8 year-old group in medical neglect level had no statistical significance, but was close to the cut-off point (P = 0.054). The test results of external validity indicated that both of the two scales could reflect the neglect status of the subjects (P < 0.05), but the subjective and objective evaluation towards neglect were not consistent. The cut-off points for judging whether the children were neglected or not among 6-8 year-old and 9-11 year-old groups were 159 and 137 respectively; and the adjusted values were 160 and 135 respectively.

CONCLUSIONThe two norm scales developed by this study showed good discriminability, reliability, validity, and stability. The norms developed on the basis of the scales was suitable for the situation of rural students in primary schools in China.

OBJECTIVEThis study quantitatively examined signal joint T-cell receptor rearrangement excision circles (sjTRECs) levels in peripheral blood of children with acute lymphoblastic leukemia (ALL) at different stages in order to evaluate the role of sjTRECs in predicting severe infection postchemotherapy.

METHODSsjTRECs levels in peripheral blood were measured by fluorescent quantitation-polymerase chain reaction in 30 children with newly diagnosed ALL, 36 children with ALL who accepted chemotherapy but were not infected, 30 children with ALL who had severe infection after chemotherapy, and 50 normal children.

RESULTSBlood sjTRECs levels in the normal group (394 ± 270 copies/103 MNC) were significantly higher than those in the other three groups (P<0.05). Blood sjTRECs levels in the chemotherapy group without infection (96 ± 78 copies/103 MNC) were significantly lower than those in the newly diagnosed ALL group (210 ± 219 copies/103 MNC) (P<0.05). The chemotherapy group with severe infection showed the lowest blood sjTRECs levels (48 ± 40 copies/103 MNC) in the four groups.

CONCLUSIONSThe measurement of blood sjTRECs levels might be helpful for predicting the occurrence of severe infection postchemotherapy in children with ALL.
